The shooter presses one button to lock on the target and squeezes and holds the trigger to arm the system. When the weapon is optimally aligned, the Networked Tracking Scope releases the guided trigger.

"Using the PGF, you can be an elite, long-range marksman in minutes," the website promises.

However, due to "overwhelming demand," the only way to purchase a PGR is to reserve a spot on the waiting list.

There are several PGR models differentiated by caliber, barrel length, chassis system, application, and ammunition. They range in price from $17,000 to $22,000.

The PGF also offers applications for smart devices. Using the TrackingPoint App, you can download and share images, complete with voice and shot data, on Facebook, Twitter, and email.

Critics argue the weapons violate the "fair chase" principle in hunting and take the skill out of target shooting. Some question whether they should be legal for civilians to own.
